Well, after the race at the track and most of the racers there are from the town i live in.today I saw unfamiliar cars parked in front of my car and when I got out from my house,they took off. After a while, those same cars crused by and checking my car out. My car is not a lady killer or the fastest. In fact, it looks like a sleeper from the out side since I had done nothing to it beside the swap and bolt on modification. I dont fell safe for my car anymore since she is park out side on the street. Please tell me which alarm system is the best . thanks.
